Insulating a crawlspace
I am replacing the windows in this room and it has turned into a gut job. This was originally a porch on my small 1905 Victorian house. It was closed in about 20-30 years ago when these louvered windows were installed. My question is how to insulate. The crawlspace concrete block walls are to the exterior, the interior walls are the original stone foundation. On the other side of the interior foundation walls is the basement, which is unconditioned but stays warm in the winter. The space was not intentionally ventilated- there were two screened holes to the outside in two different joist bays amounting to about 50 sq inches of air space total.
When I pulled up the flooring and inspected the framing, I found the space to be bone dry. There is no evidence of any mold or water damage to the joists or the underside of the original yellow pine flooring. The mudsill is in excellent shape as well.
What is the best way to go about insulating and closing this back up? Along with the crawlspace area, the joists cantilever out over the yard and that area needs to be sealed and insulated as well.
Any advice would be appreciated.
